A one-step method for the synthesis of aromatic indolizine derivatives byintramolecular 1,5-dipolar cyclization reaction of 2-(2-arylethenyl)pyridinium N-ylidesin the presence of an oxidant has been studied for the first time. In the presence ofelectron-deficient olefins, however, 2-(2-phenylethenyl)pyridinium N-ylides underwent1,3-dipolar cycloadditions and then aromatized in situ by TPCD to produce indolizinederivatives, indicating 1,3-dipolar cycloaddition proceed more readily than 1 ,5-dipolarcyclization in these conditions. Pyridinium disubstituted N-ylides, readily obtainedfrom corresponding pridinium and β-chlorovinyl ketone, underwent thermalintramolecular 1,5-dipolar cyclization to give indolizine derivatives easily.Indolizinecarbaldehyde derivatives were synthesized starting from 2-pyridinecarbaldehyde in four-steps involving 1,3-dipolar cycloaddition reaction.
本文首次研究了2-(2-芳基乙烯基)吡啶N-叶立德在氧化剂存在下的分子内1,5-偶极环化反应,采用一锅法合成了中氮茚衍生物;研究了这些N-叶立德的1,5-偶极环化和1,3-偶极环加成反应的选择性,发现当有缺电子烯烃存在时,优先进行1,3-偶极环加成反应,而不再发生分子内1,5-偶极环化反应;由β-氯乙烯酮方便地得到了烯丙基N-叶立德,他们在加热时进行分子内1,5-偶极环化反应而得到中氮茚衍生物;由2-吡啶甲醛为起始原料,通过1,3-偶极环加成反应等四步反应,得到了重要的中氮茚甲醛衍生物,这些反应都具有条件温和和操作简便的特点,是合成中氮茚衍生物的新方法。
